Jkay Posted August 12, 2010 Report Share Posted August 12, 2010 I have seen this question many times, and have wondered myself. Just a few moments ago I was re-assembling my porikaa and didn't get it quite right, so when I tried to wind it, the hands spun freely as the spring was powered up. For the record ... the minute hand moves 1hr 10mins for every revolution of the stem in winding position The seconds hand spins so quickly, it can not be seen! So there you have it .. about 70 minutes of reserve for 1 revolution of the crown, when hand-winding. Link to comment Share on other sites More sharing options...
